The 28-year-old Weber allowed just two runs in nine innings for the Friars this season, though he walked five and struck out only six in that time. The Padres claimed him off waivers from the Tigers last August. Weber has just 13 innings of big league experience and averages 89.8 mph on his fastball. He does have a stellar 68.2 percent ground-ball rate in that admittedly tiny sample.

Stauffer, 30, was a key member of the Padres' pitching staff from 2009-11. After a strong year-plus in the bullpen, he shifted to the rotation for the end of the 2010 season and all of the 2011 campaign. He made one start in 2012 before elbow surgery cut his season short. From 2009-12, the former No. 4 overall pick in the draft had a 3.27 ERA, 6.4 K/9 and 3.0 BB/9 in 346 1/3 innings of work.

Stauffer signed a minor league contract this offseason after being waiver in the fall. His deal had an opt-out clause around June 1, so the Padres were nearing a decision on him. Stauffer had a 3.16 ERA through 42 2/3 innings at Triple-A Tucson this season.
